Aplane intersects one cone of a double-napped cone such that the plane is parallel to the generating line.

explain your answer : )

what conic section is formed?

hyperbola

ellipse

parabola

circle

Third option is correct.

Step-by-step explanation:

When a plane intersects one cone of a double-napped cone such that the plane is parallel to the generating line. (here, slant height), it forms parabola.

Because  a parabola is  generated by the intersection of the regular cone with a plane.

It intersects the one cone of a double napped cone and it becomes parallel to the slant line.

Hence, third option is correct.

answer is d-29

step-by-step explanation:

since you didn't include the picture, i can give you the description so you know how to pick the correct answer. the third quartile of a data is always shown in a box plot. in the middle of your graph should be a box. the third quartile is the value that goes with the far right edge of the box.

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
